Be it known that I, ETI-IAN I. DODDs, a citizen of the United States, residing at Avalon, in the county of Allegheny, in the State of Pennsylvania, have made a new and useful Improvement in Steel Side Stakes for Cars, of which the.following is a specific ation.

My present invention relates to an economical method of forming side or end stakes for steel or wooden cars, the stakes being produced by cutting through the flanges and webs of rolled beams of channel, I, or Z crosssection. By adopting the method of manufacture described herein it becomes unnecessary to provide means for making side or end stakes as an independent or separate manufacture, it being only necessary to make use of well-known existing forms of steel bars or beams, from which stakes can be manufactured with little or no waste or scrap.

In the manufacture of side or end stakes for cars it is desirable to provide structures havin adequate strength and the smallest possibde amount of material consistent with great strength. I find that by making side or end stakes with suitable flanges for attachment to the various sections of the car side and constituting these side or end stakes in such a manner as to make the web portions flare from the top toward the bottom a structure fully adequate for the purpose is provided, the same being quite as strong as side or end stakes in which the web or projecting blade is of uniform depth or height throughout the entire length of the stake. This is true even when the uniform depth or height is equal to the maximum depth or height of the web or blade portion of the side or end stake forming the subject of the present in- .vention. Starting from this consideration I have devised a method of making side or end stakes with flaring webs 0r blades, which method is fully illustrated in the drawings herewith, wherein Figure 1 is a side elevation of a rolled 1-.

beam, illustrating the cuttings which I pro- Fig. 2 is a reduced side elevation of a similar beam, illustrating how a number of side or end stakes can be made from a single beam. 3 is a side elevation of a similar beam, showing two side or end stakes after the cutting has been accomplished. Fig. 4 is a plan view of a side or end stake. Figs. 5, 6, and 7 are end views of rolled beams of different shapes, and Fig. 8 is a side elevation of a steel car having my side or end stakes applied thereto.

In Fig. 1 of the drawings is shown a side elevation of a rolled I-beam having a bias cut a a through its web and flanges. At one end of the beam a piece of scrap a will be formed, as shown. At the proper distance a parallel out (also indicated by the characters a a) is made, and in this way a section of the I-beam is formed having the outline indicated by the central portion of Fig. 1that is to say, the portion between the two parallel cuts (indicated by the characters a a.) In order to form the said section into pieces suitable for side or end stakes, a cut (indicated by the broken line 0 c) is made, and this cut is caused to intersect the other cuttings already described at points just inside the flanges of the I-beam. In this way a small piece of scrap is left at each acute end of the cuttings, as indicated in Fig. 1 at f When a beam of considerable length is chosen, it may be cut up into a number of side stakes, depending on the length of the beam and the length selected for the side or end stakes.

In Fig. 2 I illustrate an I-beam having several cuttings sufl ioient to sever the beam into four complete side or end stakes. In this figure I also show cuttings c 0, extending through the flanges c 0 whereby the scrap (indicated at f f in Fig. 1) is done away with. In this case the cutting a a does not extend through the flanges, but only through the web and to the near sides of the flanges, at which latter points it connects with the cuttings c 0 running through the flanges.

In'Fig. 4 is represented a plan view of one of the side stakes I) complete.

The invention may be applied to rolled beams of other shapes than that illustrated in Fig. 1as, for example, channel or Z barsand the side or end stakes when made may be applied to steel cars of various types or to cars having wooden bodies.

I claim as my invention 1. The method of manufacturing side or end stakes for railway-cars from a beam having flanges at its opposite edges which consists in severing said beam into parts by cuts intersecting each other substantially in the planes of the inner surfaces of said flanges, substantially as described.

2. The method of maln'ng side or end stakes for railway-cars from a beam having flanges at its opposite edges Which consists in severing said beam into parts by cuts extending through said flanges and intersecting each other substantially in the planes of the inner surfaces of said flanges, substantially as described.

3. The method of manufacturing side or end stakes for railway-cars from a beam having flanges at its opposite edges which consists in cutting through said flanges at suitable points and dividing the Web of said beam by cuts which intersect each other substantially in the planes of the inner surfaces of said flanges at the points where the latter are cut through, substantially as described.
